Loop start trunks are available on the IP Office Analog Trunk cards installed within the IP Office control

unit, or on the Analog Trunk 16-port expansion modules (ATM16). The first two trunks on the ATM16 are

TIA/EIA-646-B standard. The loop start trunks also support incoming caller line identification (ICLID)

or provide it to computer applications to display additional information about the caller.

Ground Start trunks are only available on the ATM16, configured through IP Office Manager. The first two

trunks on the module are automatically switched to power fail socket in the event of power being

interrupted. They conform to ANSI T1.401 and TIA/EIA-646-B standards. Not available in all territories.
